Algebra.Com's Answer #327521 by Theo(13342) You can put this solution on YOUR website! if the problem is worded correctly, then -m - 55n - 65p is not your answer. \n" ); document.write( "you want to subtract (17m - 37n + 46p) from (-16m + 18n - 19p) \n" ); document.write( "in equation form, that reads as: \n" ); document.write( "(-16m + 18n - 19p) - (17m - 37n + 46p) \n" ); document.write( "remove parentheses to get: \n" ); document.write( "-16m + 18n - 19p - 17m + 37n - 46p \n" ); document.write( "combine like terms to get: \n" ); document.write( "-33m + 55n - 65p \n" ); document.write( "if your answer is supposed to be -m - 55n - 65p then something is wrong with the expressions. \n" ); document.write( "if you had (16m - 18n - 19p) - (17m + 37n + 46p) then you would get an answer that looks like -m - 55n - 65p \n" ); document.write( "you would remove parentheses to get 16m - 18n - 19p - 17m - 37n - 46p \n" ); document.write( "you would combine like terms to get: \n" ); document.write( "-m - 55n - 65p \n" ); document.write( "based on the way you presented those expressions, there's no way you're going to get -m - 55n - 65p if you subtract one from the other. \n" ); document.write( "even if you reversed the subtraction to get: \n" ); document.write( "(17m - 37n + 46p) - (-16m + 18n - 19p) you would wind up with: \n" ); document.write( "remove parentheses to get: \n" ); document.write( "17m - 37n + 46p + 16m - 18n + 19p which would then become: \n" ); document.write( "33m - 55n + 65p \n" ); document.write( "it's not possible to get -m - 55n - 65p the way the problem is originally presented.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
